There have been some concerns about using Borax as an ingredient in making slime, so we’ve got an alternative that is safer for kids – contact lens saline solution!

Slime is really fun and the making of it is quite an entertaining activity for kids. My girls 7 & 5 try to do it as much as they can. We have also bought some pretty inexpensive ones to try to replicate. Replicating slime is now our thing or coming up with the craziest contraptions we can.

How to Make Slime

Mix the saline solution into your slime until it starts to form together

Now you have slime! Mould it into different shapes and have fun with different colour options. You can store the slime in plastic containers to use later, but it’s best and most fun to play with right after it’s made.

Slime Tips

If your slime won’t stick together, try adding more contact solution so it bonds together better. If it is too sticky, you can add more baking soda. If it is too hard and not flexible, you may have added too much contact solution. Knead the slime and work it through your hands really well to see if it loosens up. If not, we recommend making a smaller batch of slime with 4 oz of glue and 1/2 tbsp baking soda, and then 1 tbsp of contact solution. Mix together and add more contact solution if needed.

PLEASE NOTE: Adult supervision is recommended for this activity. Although contact lens saline solution is a safer option than Borax, it does still contain Boric Acid, and should not be ingested.
